The idea of church being an organisation bent on control is a pretty well established one. It's one of the reasons I dislike organised religions.

And most of the symmetry they demonstrated could easily be explained by coincidence (after all, there's also a great deal of great wonders that fall outside the described pattern).

The stories about inter-dimensional beings was more the stuff that had me curious. I've often said that if a God-like deity existed, it would have to live outside our 3.1* dimensional plane to fit what we would describe as omnipotent. However the problem with stories like these is they're based almost entirely on speculation.

(*3 dimensions + time)

I also don't like stories that tie psychic phenomena into 3 dimensional beings. Almost always, what people perceive as psychic behaviours are either:

1) retrospective interpretation (eg selective memories such as "I thought something felt odd" when they experience that feeling often but only remember the occasions that links into an event, and how Nostradamus's predictions are re-interpreted post-event to match up with historic events, but never interpreted "correctly" pre-event)

3) "psychosomatic" (ie if you want to believe something badly enough, then you'll feel non-existent connections and notice things that don't exist. A lot like how placebo drugs can fool the patient into believing they have all manor of side-effects.

4) blind luck / coincidence (people are sometimes so keen to believe in a higher power -be that a deity or other supernatural powers- that they'll say the phrase "it's too much of a coincidence not to be xyz" - when in actual fact, coincidences happen all the time)

All that aside, this is one of the less wacky "theories" that I've heard. And certainly interesting enough to make me keen to investigate it further.
